    • The image processing circuit essentially includes an image data input portion, an image processing portion, an image data output portion, an image memory composed of a hard disk drive etc., a central processing unit (CUP), an image editing portion, an external interface portion. Based on the determination result of the laser recording status determination by the CPU, an LCU also serving as a mirror motor control device, stops or retards the drives of driving motors, one by one, in the order of their completion of laser recording. The image processing circuit may further has a mode manager for checking the usage frequencies of the first most processing mode in which the input image information is image processed as color image information and the second processing mode in which the input image information is processed as monochrome image information. Moreover, the image processing portion may further has an original discriminating portion for determining the color type of an original.
    • 图像处理电路基本上包括图像数据输入部分,图像处理部分,图像数据输出部分,由硬盘驱动器等组成的图像存储器,中央处理单元(CUP),图像编辑部分,外部 接口部分。 根据由CPU确定的激光记录状态的确定结果,也用作镜面电动机控制装置的LCU按照其完成激光记录的顺序逐个地停止或延迟驱动电动机的驱动。 图像处理电路还可以具有模式管理器,用于检查输入图像信息被图像处理的第一最多处理模式的使用频率作为彩色图像信息,以及将输入图像信息作为单色图像处理的第二处理模式 信息。 此外,图像处理部分还可以具有用于确定原稿的颜色类型的原始识别部分。

    • A plurality of first base images for a base color are formed in accordance with a predetermined adjustment value. A plurality of first correction images for a correction color to be a subject for correction are formed on the first base images in accordance with a predetermined adjustment value. The first correction images are displaced within a predetermined range. The first adjustment value is determined from changed adjustment values. The second base images for the base color are formed in accordance with the predetermined adjustment value while the second correction images for the correction color are formed in accordance with a plurality of adjustment values determined based on the first adjustment value. One second adjustment value having an extreme is determined from the plurality of adjustment value candidates. These processes are repeated to determine a final adjustment value. The adjustment value for the correction color is corrected to the determined final adjustment value.
    • 根据预定的调整值形成用于基色的多个第一基础图像。 根据预定的调整值,在第一基本图像上形成用于校正对象的校正颜色的多个第一校正图像。 第一校正图像在预定范围内移位。 第一个调整值由改变的调整值确定。 根据预定的调整值形成基色的第二基础图像,同时根据基于第一调整值确定的多个调整值形成用于校正颜色的第二校正图像。 从多个调整值候选确定具有极值的一个第二调整值。 重复这些处理以确定最终调整值。 校正颜色的调整值被校正到所确定的最终调整值。
